1、Longer Lives Are Happier Lives1 In recent years, scientists have been studying ways to change the body\'s chemistry to reduce the signs ａｎｄ　effects of aging.2 0neｇｒｏｕｐof researchers in Britain has performed experiments on a kind of worm. They have managed to increase the worm\'s normal life span of 20 days by up to 400%. They hope that they will be able to use this research to help humans live longer. However, this is a long way in the future. Another disadvantage is that when (ｏｒif) the new technology is successfully developed, it will probably be very expensive. The chance to live longer will only be available to a very few, very rich people.3 Anotherｇｒｏｕｐof scientists is studying people who have reached a very old age. They believe that this may show what has kept these people healthy ａｎｄ　alive fｏｒso long. So, if we look at people who have lived into very old age, what do they have in common? Usually they have led a physically active life. This does not mean going to a gym ｏｒrunning ten miles every day. Simple, enjoyable activities like walking seem to be more likely to keep you healthy. Very old people also eat a good, varied diet. Simple foods like vegetable, rice, pasta ａｎｄ　fish are the best.4 However, there may be one thing even more important than physical factors like diet ａｎｄ　exercise. Research shows that personality, ａｎｄ　the way a person thinks, play an important part in how long they will live. People who live into very old age always seem to enjoy life. They have a sense of humｏｒａｎｄ　get satisfaction from simple things. They do not constantly think about the past, but are interested in the present ａｎｄ　the future. They do not let life get boring, but have interests ａｎｄ　hobbies which keep their minds active ａｎｄ　they are open to new ideas. One Japanese man who lived to be 120 commented that the secret of his long life was "not worrying". To express it simply, people who are happy ａｎｄ　positive about life are more likely to live longer.5 So, eat well, exercise well, ａｎｄ　enjoy life, ａｎｄ　you will have a good chance of living to a healthy, happy old age.Paragraph 3 ____【单选题】

A.How to live happy old age

B.Disadvantages of the project

C.The study of old people

D.Personality ａｎｄ　other mental factors are more important

E.Worms live longer than humans

F.Live simple lives

正确答案:C

答案解析:首句，另一组科学家正在研究长寿老人，这是对整段的概述，接下来，发现了他们的共同之处。因此选C。

2、A Strong Greenhouse Gas1 Methane is a colorless, odorless gas; it is also a potent greenhouse gas, ａｎｄ　once released into the atmospheres, it absorbs beat radiating from Earth\'s surface. That\'s why methane is a majｏｒcontributｏｒto the planet\'s increasing temperature rise ｏｒglobal warming. Molecule fｏｒmolecule, methane\'s heat-trapping power in the atmosphere is 21 times stronger than carbon dioxide, the most abundant greenhouse gas.2 With 13 billion cows belching almost constantly around the world (100 million in the U. S. alone), it\'s no surprise that menace released by livestock is one of the chief sources of the gas. Other prime methane sources: petroleum, drilling, coal mining, solid-waste landfills ａｎｄ　wetlands.3 Greenhouse gases like methane ａｎｄ　carbon dioxide make up only a small part of Earth\'s atmosphere, which is 78 percent nitrogen ａｎｄ　nearly 21 percent oxygen. ａｎｄ　without greenhouse gases to trap the sun\'s heat ａｎｄ　warm the planet, life as we know it couldn\'t exist. But in the last200 years, human activity that requires burning oil, natural gas, ａｎｄ　coal fｏｒenergy has magnified the greenhouse effect.4 Atmospheric concentrations of methane have more than doubled in the last two centuries. Blame fｏｒthis often focuses on big industries ａｎｄ　gas-guzzling vehicles. But agriculture plays a majｏｒrole, too. In the past 40 years alone, the global cattle population has doubled.5 Cows munch mostly grasses ａｎｄ　hay yet they grow big ａｎｄ　hefty. Why? Because of the rumen. The rumen holds 160 liters of food ａｎｄ　billions of microbes. These microscopic bacteria ａｎｄ　protozoa break down cellulose ａｎｄ　Fiber into digestible nutrients. A cow couldn\'t live without its microbes. As the microbes digest cellulose, trey release methane. The process occurs in all animals with a rumen (cows, sheep, ａｎｄ　goats, fｏｒexample), ａｎｄ　it makes them very gassy. It\'s part of their normal digestion process. When they drew their cud, they regurgitate some food to rechew it, ａｎｄ　all this gas comes out. The average cow expels 600 liters of methane a day.That\'s why we say livestock gas is also a majｏｒfactｏｒof causing the global warming.Generally people heap criticism on fox the planet\'s temperature rise ____ .【单选题】

A.one of tire majｏｒcontributors

B.the ever-increasing atmospheric concentration of greenhouse gases

C.big ａｎｄ　hefty cows

D.livestock\'s normal digestion process

E.how to cut down the cattle population

F.big industries ａｎｄ　gas-guzzling vehicles

正确答案:F

答案解析:第4段第2句直接谈到这个问题，人们常常将不断加剧的温室效应归罪于大工业和汽车，而cattle释放甲烷的因素被忽略了。

3、She gave up her job ａｎｄ　started writing poetry.【单选题】

A.lost

B.abandoned

C.took

D.created

正确答案:B

答案解析:题干大意：她放弃了工作，开始写诗。句中give up的意思是“放弃”。如：In view of the circumstances，we should give up the plan.（考虑到情况的变化，我们应该放弃这项计划）。abandon:放弃，如：After the age of thirty he abandoned individual ambition.（他一过30岁就放弃了个人的雄心壮志。）lose:丢失；take：拿；create：创造。

4、Geology ａｎｄ　Heap(1)The importance of particular metals in the human diet has been realized within the past few decades, ａｎｄ　the idea that geology might be related to health has been recognized fｏｒa number of elements such as iodine, zinc ａｎｄ　selenium. Fｏｒexample, soils with low iodine contents produce crops, ａｎｄ　animals deficient in iodine. A lack of iodine in the human diet leads to some serious diseases.(2)The ultimate source of metals within the human body is rocks, which weather into soil, gaining ｏｒlosing some of their chemical constituents. The crops we eat selectively remove from the soil the elements that they require fｏｒgrowth. The water we drink contains trace elements leached from rock ａｎｄ　soil. Thus the geology ａｎｄ　geochemistry of the environment have effects on the chemistry ａｎｄ　health of plants, animals ａｎｄ　people.(3)So far there is no data to suggest that people living on metal-rich soils experience a potential health hazard. The levels of metals within naturally contaminated soils are generally not high enough to cause serious health problems. Living on metal-rich soils does not represent a health risk unless large quantities of soil are digested ｏｒmetal-rich dust is inhaled. However, small children are particularly exposed to metal-rich topsoil in playgrounds ａｎｄ　gardens. They are also the most likely ones to eat potentially dangerous metal-rich soil.(4)Heavy metals are persistent: they do not break down to other chemicals in the environment. Industrially polluted sites usually undergo intensive clean-up ａｎｄ　rehabilitation because heavy metals are a health concern once they enter the food chain. Some trace metals are alleged to cause cancer ａｎｄ　are also known to cause poisoning(5)In contrast, naturally contaminated soils have not been subject too risk assessment studies ａｎｄ　rehabilitation measures, despite the fact that they frequently possess metal concentrations well above those of such polluted by humans ａｎｄ　above environmental quality criteria.(6)There is a vital need to understａｎｄ　the potential risks ａｎｄ　long-term health effects of living on naturally contaminated soils. Future environmental investigations of naturally polluted soils should concentrate on the potential pathways of metals into the food chain ａｎｄ　human body. Geologists should be part of such studies as they can provide the essential background information on rock ａｎｄ　soil chemistry as well as the chemical forms of heavy metal pollution.Some serious diseases is connected with deficiency of ____【单选题】

A.industrially polluted soils

B.rock ａｎｄ　soil chemistry

C.naturally polluted soils

D.the pathways of metals into the food chain

E.the element of iodine

F.the persistence of heavy metals

正确答案:E

答案解析:第1段最后一句“A lack of iodine in the human diet leads to some serious diseases”是选择E的依据。

5、What are my chances of promotion if I stay here?【单选题】

A.retirement

B.advertisement

C.advancement

D.replacement

正确答案:C

答案解析:如果我还待在这干，我有升职的机会吗？promotion指“提升，晋级”，和advancement的引申意义“晋升”是同义词，A项指“退休”，B项指“广告”，D项指“代替”，三项的干扰性不强。本题考查的是advancement的引申意义。
